In July 2020, the European Telecommunications Standards Institute (ETSI) Quantum-Safe Cryptography (QSC) working group released Technical Report TR 103 619, defining migration strategies and recommendations for quantum-safe schemes. The report provided a framework of actions that organizations should take to enable migration to a Fully Quantum-Safe Cryptographic State (FQSCS).
TR 103 619 outlined a three-stage migration approach. Stage one addressed inventory compilation, requiring organizations to identify cryptographic assets and processes that could be affected by quantum computing. Stage two covered preparation of a migration plan, including dependency analysis and testing. Stage three dealt with executing the migration itself, including mitigation management and progress tracking.
According to ETSI, the report recognized that the threat of quantum computing to asymmetric cryptography is an existential risk to business sectors that rely on such cryptography. The working group stated that knowing a quantum-safe algorithm exists is not sufficient and that entire businesses must be ready to migrate.
